Bug #31687	Error in my_thread_global_end(): 1 threads didn't exit

Description:
I compile the mysql odbc 3.51.21 by myself, the mysql server i used is server 5.1.21. Then i run the tests against the myodbc(use the testcases in mysql-connector-odbc-3.51.21\test\ ). 

The test result like this: 

D:\mysql-connector-odbc-3.51.21\test\release>my_bulk.exe mysql root 111111
1..4
# Total rows fetched: 1600
ok 1 - t_bulk_insert
# Total rows fetched: 3
ok 2 - t_mul_pkdel
ok 3 - t_bulk_insert_indicator
ok 4 - t_bulk_insert_rows
Error in my_thread_global_end(): 1 threads didn't exit

I known that these is a server's bug(bug#25621) related with this error, but it had been fixed in this version, hadn't it?  Why does the error recur? 

How to repeat:
compile the myodbc 3.51.21 with mysql server 5.1.21, then run the regressive testsuite.

Hello Ming Lu,

thanks for writing a bug report.

Unfortunately, I can't reproduce this problem. The test works fine here.

How did you compile the driver?

Please, try also MyODBC version 5.1.

My compile environment:
      Windows 2000 Advanced Server (SP4)
      VS .net 2003
      qt 3.3.2
      cmake 2.4
      bison 2.1
      MySQL Server 5.1.21

Btw, I find the same error when starting the mysql server 5.1.22 by command-line mode. The test like this:

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqld.exe --defaults-file="c:\program files\mysql\mysql server 5.1\my.ini" --console

Error in my_thread_global_end(): 1 threads didn't exit

When the server started, i didn't do any operation against the server, then i shutdown the server by 'crtl+c' in command-line mode.

Hi Ming Lu,

thanks for your details. I can reproduce this.

Regards,

Susanne

I am also getting this error message (my_thread_global_end()). My server version is 5.0.27-community-nt, odbc driver is 3.51.21-win32.msi. My development tools are MS visual Studio 2003 (unmanaged C++) in Windows XP. I am using Boost C++ libraries 1.33.1 (threads and other libraries) with Microsoft OLE DB driver for ODBC to connect MySQL database. My program used to work fine before installing this new version of ODBC driver. I will appreciate any update about this bug report.

Compiling Connector/ODBC 3.51.21r807 from source and linking with libraries from MySQL 5.0.48 corrects the problem. 

Only the driver (myodbc3.dll) needs to be replaced, so TrollTech Qt isn't needed to do this. I used Visual Studio 2005 SP1.

Apparently MySQL versions 5.0.44 and later are fixed. Unfortunately the Windows downloads for Connector/ODBC versions 3.51.16 through 3.51.21 appear to be linked with a version of MySQL which was not fixed - so they still show the 'threads didn't exit' message.

Re-build odbc driver on windows for MySQL server v 5.0.45 not successful.
I cannot find a win32 binary version of v5.0.48 (only for Enterprise version, please advise)  Thanks all.

Link error : 
1>mysqlclient.lib(my_compress.obj) : error LNK2019: unresolved external symbol _compress referenced in function _my_compress_alloc
1>mysqlclient.lib(my_compress.obj) : error LNK2019: unresolved external symbol _uncompress referenced in function _my_uncompress
1>C:\download\src\odbcsvn\trunk\lib\Debug\myodbc3.dll : fatal error LNK1120: 2 unresolved externals

How to reproduce:

use server version 5.0.45 (zip file, no install version from download site)
use odbc3.51.21r807 (from download site)

use cmake 2.4.7, vs 2003 .net v7.1.6030
follow the BUILD.win in myodbc source dir and use cmake to generate solution file. omitting QT library.

in vs2003, choose project myodbc3, build.... error appears

My Doubt:
it's a bug in mysqlclient.lib, 
Can anyone please confirm (or disconfirm) this and give suggestions?

Additional info:
Link parameters in vs2003

Building 5.0.48 requires getting the source via BitKeeper, 
  see http://dev.mysql.com/doc/refman/5.0/en/installing-source-tree.html

This error message appears to have been fixed for mysqld in 5.0.44 
   http://lists.mysql.com/commits/25160

The fix for client apps (like ODBC) which link with mysqlclient.lib was not made until Aug 16, 2007, so it is not fixed in the 5.0.45 mysqlclient.lib.
   http://lists.mysql.com/commits/32641 
   search for "+#ifdef HAVE_PTHREAD_KILL"

The client fix just suppresses the message for platforms which don't have HAVE_PTHREAD_KILL (like Windows).  The driver still pauses on exit for 5 seconds waiting for all the threads to end.

As a temporary measure to use Connector/ODBC 3.51.21 you could:
* put the #ifdef around lines 181-184 in the MySQL 5.0.45 source file: mysys\my_thr_init.c
* re-build MySQL to create a new mysqlclient.lib
* re-link myodbc3 with this new mysqlclient.lib

I get the same faulty error message on my win2k under MinGW with libmysql.dll from both recent 5.1.22-rc and 5.0.45 official windoze builds. There is no such an issue with libmysqlclient_r at least on Linux.

This should be a duplicate of Bug#25621.

Is this a duplicate bug?
Bug #25621 had been closed, why the same error still occur in mysql server 5.1.21&5.1.22 ?

Thank you for your bug report. This issue has been committed to our source repository of that product and will be incorporated into the next release.

If necessary, you can access the source repository and build the latest available version, including the bug fix. More information about accessing the source trees is available at
